# Health Equity and Social Determinants in OB/GYN

## Introduction

Health equity -- the principle that every person should have a fair opportunity to attain their full health potential -- remains unrealized in obstetrics and gynecology. Persistent disparities in maternal mortality, preterm birth, cervical cancer survival, and access to contraception disproportionately affect Black, Indigenous, Hispanic, and other marginalized communities. These disparities are driven not by biology alone but by the social determinants of health (SDOH) and structural factors that shape the conditions in which people are born, live, work, and age. Addressing health equity is both a clinical competency and an ethical obligation for OB/GYN physicians.

## Social Determinants of Health

### Framework

Social determinants of health are the non-medical factors that influence health outcomes, accounting for an estimated 50-80% of health outcomes -- far exceeding the contribution of clinical care (approximately 10-20%). Healthy People 2030 identifies five key domains. Economic stability encompasses poverty, employment, food security, and housing stability. Education access and quality includes literacy, language, and educational attainment. Healthcare access and quality involves insurance coverage, provider availability, and cultural competency. Neighborhood and built environment covers housing quality, transportation, environmental exposures, safety, and food deserts. Social and community context addresses social cohesion, discrimination, incarceration, and immigration status.

### SDOH in Obstetrics and Gynecology

Insurance status profoundly shapes outcomes: uninsured and Medicaid-insured women have higher rates of late prenatal care initiation, preterm birth, and maternal mortality. The traditional Medicaid pregnancy coverage ending at 60 days postpartum creates a dangerous gap, given that one-third of maternal deaths occur between 1 week and 1 year postpartum. Food insecurity affects 17% of pregnant women in the US and is associated with gestational diabetes, preeclampsia, low birth weight, and preterm birth; WIC (Women, Infants, and Children) participation improves birth outcomes. Housing instability and homelessness are associated with inadequate prenatal care, substance use, preterm birth, and low birth weight. Transportation barriers particularly affect rural women, who may travel 60 or more miles to reach an obstetric provider; these barriers correlate with missed appointments, delayed emergency care, and higher rates of adverse outcomes. Incarcerated women face limited prenatal care access, shackling during labor (still legal in some states), restricted contraceptive access, and disrupted mother-infant bonding.

## Racial and Ethnic Disparities in OB/GYN

### Maternal Health Disparities

Black women die at 2.6 times the rate of White women from pregnancy-related causes, and American Indian/Alaska Native women at 2.0 times; these disparities persist after adjusting for education, income, comorbidities, and insurance status. Black women experience severe maternal morbidity at 2.1 times the rate of White women, with disparities widest for transfusion-related and hypertension-related morbidity. The preterm birth rate for Black women is 14.4% compared to 9.4% for White women, a disparity that contributes significantly to the Black-White infant mortality gap. Black women have higher primary and total cesarean delivery rates, even after controlling for medical indications, with disparities in TOLAC access and success contributing to this gap. Black and Hispanic women are less likely to be screened for and diagnosed with postpartum depression despite similar or higher prevalence rates.

| Outcome | Black Women | White Women | Disparity Ratio | Contributing Factors |
|---|---|---|---|---|
| Pregnancy-related mortality | ~70/100,000 | ~27/100,000 | 2.6× | Structural racism, implicit bias, weathering, delayed care |
| Severe maternal morbidity | 2.1× higher | Reference | 2.1× | Hypertension-related and transfusion-related disparities |
| Preterm birth rate | 14.4% | 9.4% | 1.5× | Chronic stress, neighborhood factors, infection |
| Cesarean delivery rate | Higher | Reference | Elevated | Disparities in TOLAC access, provider decision-making |
| Postpartum depression screening | Lower rates | Reference | Under-detected | Screening bias, access barriers |

### Gynecologic Health Disparities

Black and Hispanic women have higher incidence and mortality from cervical cancer, driven by differences in screening rates, follow-up of abnormal results, and treatment access. Black women develop uterine fibroids at younger ages with greater symptom severity, larger tumor burden, and higher rates of hysterectomy, yet they are less likely to be offered uterine-sparing treatment options such as myomectomy or uterine artery embolization. Black women have lower incidence but significantly higher mortality from endometrial cancer, with higher rates of aggressive histologic subtypes (serous, clear cell) and later-stage diagnosis. Geographic and financial barriers to contraceptive access disproportionately affect low-income women and women of color, with contraceptive deserts (counties without access to the full range of methods) affecting millions. Historical and ongoing patterns of forced sterilization of Black, Indigenous, and disabled women have created justified mistrust; awareness of this history is essential for providing respectful, patient-centered contraceptive counseling.

## Structural Racism and Health

### Mechanisms

Structural racism refers to the totality of ways in which societies foster racial discrimination through mutually reinforcing systems of housing, education, employment, healthcare, and criminal justice, producing and perpetuating inequities across generations. Residential segregation, created by historical redlining policies, concentrates poverty, limits access to healthy food and safe environments, and reduces proximity to quality healthcare facilities. Implicit bias -- unconscious attitudes and stereotypes that affect clinical decision-making -- has been demonstrated in studies showing that Black patients receive less pain medication, are less likely to receive epidural anesthesia in labor, and experience more dismissal of reported symptoms. The weathering hypothesis, proposed by Geronimus, holds that chronic exposure to social and economic adversity and discrimination accelerates biological aging through allostatic load (chronic stress-mediated physiologic wear), contributing to higher rates of hypertension, preterm birth, and cardiometabolic disease among Black women, even among those with higher socioeconomic status. Medical mistrust is rooted in historical abuses including the Tuskegee syphilis study, J. Marion Sims' experiments on enslaved women, and forced sterilization programs; this mistrust affects healthcare utilization, adherence, and willingness to participate in research.

### Impact on Clinical Care

Pain management disparities mean that Black patients are less likely to receive adequate pain management in emergency and postoperative settings. Symptoms reported by Black women are more likely to be minimized or attributed to non-organic causes, leading to diagnostic delays. Treatment disparities persist: Black women with fibroids are more likely to be counseled toward hysterectomy than myomectomy compared to White women with similar clinical profiles. Women of color remain underrepresented in obstetric and gynecologic clinical trials, limiting the generalizability of evidence to diverse populations.

## Screening for Social Determinants

Universal SDOH screening at prenatal and gynecologic visits is recommended by ACOG, AAP, and numerous professional organizations. Validated tools include the PRAPARE (Protocol for Responding to and Assessing Patients' Assets, Risks, and Experiences) tool, which assesses 16 SDOH domains, as well as simpler instruments like the 2-item food insecurity screen and the single-item housing instability question. Key domains to screen include food insecurity, housing instability, transportation barriers, interpersonal violence, substance use, depression/anxiety, financial strain, and social support. Crucially, screening must be paired with resources -- practices should maintain updated referral lists for local social services, WIC, SNAP, housing assistance, legal aid, and behavioral health. Many systems use community health workers or patient navigators to facilitate connections between patients and community resources.

## Strategies for Advancing Health Equity

### Clinical Practice

Implicit bias training is a first step, with structured programs developed by organizations such as the March of Dimes and ACOG helping providers recognize and mitigate unconscious biases in clinical decision-making. Standardized clinical protocols reduce variation in care that may be influenced by bias, with examples including standardized criteria for labor induction, cesarean delivery, and pain management. Patient-centered communication encompasses shared decision-making, teach-back methods, and use of professional interpreters (not family members) for patients with limited English proficiency. Diversifying the workforce matters because concordance between patient and provider race/ethnicity is associated with improved patient trust, communication, and outcomes -- studies show that Black women receiving care from Black physicians have lower rates of maternal and infant mortality.

### Community-Level Interventions

Group prenatal care (CenteringPregnancy) reduces preterm birth among Black women, improves patient satisfaction, and enhances health literacy and social support. Community doula programs provide continuous labor support that reduces cesarean delivery rates, improves birth satisfaction, and narrows racial disparities in outcomes; Medicaid coverage for doula services is expanding in many states. Community health workers -- individuals from the communities they serve -- provide culturally concordant education, navigation, and support, and are effective in improving prenatal care utilization and reducing preterm birth among underserved populations. Birth equity collaboratives at state and regional levels, such as the California Maternal Quality Care Collaborative and various Perinatal Quality Collaboratives, implement equity-focused quality improvement initiatives.

### Policy-Level Interventions

Extending Medicaid coverage from 60 days to 12 months postpartum addresses a critical coverage gap and has now been adopted by most US states. Contraceptive access policies including Title X funding, removal of cost-sharing barriers, and same-day LARC placement policies improve contraceptive equity. Anti-shackling legislation prohibits the use of restraints on pregnant and postpartum incarcerated individuals. Data disaggregation -- collecting and reporting outcome data stratified by race, ethnicity, language, insurance status, and geography -- is essential for identifying and tracking disparities. Addressing maternity care deserts is urgent: 36% of US counties have no hospital with obstetric services, and telehealth, midwifery expansion, and birth center development can partially address these access gaps.

## Clinical Pearls

Social determinants of health account for 50-80% of health outcomes, meaning clinical care alone cannot eliminate disparities. Black maternal mortality disparities persist at every education and income level, pointing to the role of structural racism and chronic stress (weathering) rather than individual risk factors alone. Universal SDOH screening at prenatal and gynecologic visits should be paired with actionable referral pathways to community resources. Standardized clinical protocols reduce the influence of implicit bias on care delivery decisions. Diversifying the OB/GYN workforce and expanding community-based models of care (doulas, group prenatal care, community health workers) are evidence-based strategies for narrowing disparities.
